There's a decent chance the 1997 Kuraray Faces pressing was also SuperNTSC:

As an aside, I just looked at side 1 of the DC, pressing quality seems good but the mastering does have some oddities - no "white flags" for indicating start of frame (probably part of the MCA spec, but still odd) - and especially odd for a THX disk, not much of a VITS! Just a bit with 100IRE and a drop to 0 in the middle. No THX test signal line or standard NTSC test lines either.
